Bank Mynas are known to nest in natural environments, but they can also adapt to urban areas like parks and gardens. For creating a suitable habitat in gardens, ensuring the availability of safe nesting spots and some shrubby cover can encourage nesting.
Eggs and chick-rearing
A typical Bank Myna clutch consists of three to five eggs. Both parents share incubation duties over a period of approximately two weeks. After hatching, chicks are cared for by both parents, who diligently feed them regurgitated food. Parental involvement is crucial during the initial weeks as the young are altricial, meaning they hatch in a helpless state. Fledging occurs around three weeks after hatching, and the juveniles soon begin joining the flock in foraging activities.
